Afghans using multicolor yarn

So I recently acquired a bunch of multicolored yarn and I would like to make an afghan out of it. Does anyone have any patterns that look good with multicolored yarn? And maybe some pictures too? Thanks so much!

I made my hubby (who is warm most of the time) a large granny square afghan using multicolored yarn in earth-tones. He loves it!!!! The open pattern of the granny keeps him just warm enough to be comfortable when he falls asleep on his chair.Here is the link for a picture- hope it comes thru.

I would definitely suggest using a matching solid color with your afghan. With a multicolor yarn, you won't be able to see the afghan pattern. It will just become lost in all the color. I always use a matching solid with variegated yarn.
